   Except for *some* FTTH deployments, everyone in a city area gets the   
   same "broadcast" on the coax.  The coax signals come from a combination   
   from the CMTS (which handles data) and the video head end (which   
   produces both analogue and digital TV signals). Every thing is packed   
   into 6mhz chunks which correspond to the bandwidth for the old NTSC   
   analogue TV channels.   
      
   For most cableco FTTH deployments, they use RFoG which basically means   
   that you have digital signals converted to analogue RF and then   
   converted to digital light. At the home, you get a fibre to coax output   
   with analogue RF to the DOCSIS modem and your TV set top box which then   
   process 6mhz channels as data, analogue TV or digital TV.   
      
   For some FTTH cable deployment, they really use a GPON/ethernet system   
   and deliver IPTV system and no RF/coax compatible gear. This comes off   
   totally different equipment and has no analogue channels at all.   
      
   Telcos, not having any investment in RF equipment like the cable   
   companues will generally go the GPON route with IPTV. The big exception   
   is Verizon which opted for RFoG and GPON data. (4 wavelengths total, 2   
   for RFoG (one for upstream data) and 2 for internet (down/up)
